REFRIGEBATOR.

dpplioation nlcd September 11, 1922. Serial Nb. 587,378.-

To all wwm it may concern.:

Be it known that I, Kme Gross, a citizen of the United States, residing at' Wellman, in the county of Washington and State of Iowa, have invented new and .useful lmprovementsin Refrigerators, of whichv the following is a s eciication.

The object o -my said invention -is the provision of a refrigerator which .is, at once, sim le and inexpensive in construction and hig ly eicient in on-heat-conducting ca acity, whereby it is' adapted with or wit out the assistance of ice to preserve its contents in a wholesome state for an indenite period of time. U' y To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specicationz- Figure 1 is a side elevation, partly section, of a refrigerator constructed 1n accordance with my invention.

Figure 2 is a vertical diametrical section of the same.

Fi re 3 is a horizontal section taken in the p ane indicated by thev line 3-3 of Fig-y ure 1.

Figure 4 is a detail vertical section taken on the line 4--4 of Figure 1.

Fi res 5 and 6 are detail views of a mod' ed door construction hereinafter explicitly referred to.

Similar numerals designate corresponding parts in Figures 1 to 4 to which reference will first be made. j

Among other elements my novel refrigerator comprises a casing body 1, preferably of general cylindrical form and made of galvanized iron or other appropriate met-al. At its up er end the said casing body 1 is providewith an inwardly directed flange 2. The inner side of the casing body 1 is lined with quicksilver, as designated by 3, Figure 2, with'a view to increasing its ability in preventing the passage of heat.

Within the metallic casing body or jacket 1 and snugly tting the same is a comparatively thick lining 5 of hard material conductive in character and susceptible of being easily cleaned, such as glass, porcelain, arti# icial stone, vitried earthenware, granite or equivalent material. The said lining is provided yat its u per end with an inwardlyreaching annu ar ange 5 which 'is of a greater width than the ange 2 in about the proportion illustrated. Att-'intervals in its height the lining 4 is provided with interior lugs 6 to support appropriate shelves 7,' and with upper interior lugs 8 to support an annular pan 9 from which a drain pipe 10 extends downwardly to an aperture 11 in the side wall of the refrigerator body and outwardly through the aperture, a gasket 12 or appropriate packing being employed in the aperture and about the pipe to prevent the paage of air. Spaced above the pan 9 is a latform 13 for ice, when ice is to be used 1n the refrigerator, the said platform being supported by legs 14 which are superimposed on the bottom of the pan so as to permit the free passage of cold. air downwardly 'from the ice. p

Door openings 15 areA provided in the body of the refrigerator, Figure 1, and arcuate slidable doors '16 are employed to normally close said openings; the doors being constructed in the same manner as the refrigerator body, Figure 4, 'for non-heatconducting purposes, and the joints be-l tween the doors and the refrigerator body beln broken to form an air lock as designate by 17. I would also have it understood at this point that the lining 4 is recessed at its inner side, as designated by 18 in- Figure 3, in order to accommodate the doors when opened, and that the upper and lower walls of the said recesses 18 are grooved as indicated by 19 to receive and guide the tongues on the doors. At 20 are handles on thedoors.

The upper end of the lining 4 is closed by a cover 21 of the same material as the lining, the said cover being threaded and removably secured -in the ange 5, as designated by 22, and being equipped with an ap ropriate handle 23.

nclosing the upper end of the refrigerator body is a cap 24 removably arranged over said end and formed by preference of metal and preferably lined with quicksilver as designated by 25.--

I prefer in practiceto employ the doors 16 constructed and arranged in the manner shown and described. I do not desire, however, to be limited to said Vdoors inasmuch as it is within the purview of my invention as defined by some of my claims to em loy threaded doors-16x such as shbwn in Figures 5 and 6 or doors of any other suitable description.

It will be apparent from the foregoing that my. novel lrefrigerator notwithstanding its practical advantages is simple and inexpensive in construction and is susceptible of being manufactured with facility.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiments of my invention in order to impart a full, clear and exact understanding of the said embodiments.

I do not desire, however, to be understood as confining myself to the'speciic construction and relative arrangementvof parts inasmuchas in the future practice of the invention various changes and modifications may be made such as fall Within the scope olf 'my invention as defined in my appended c alm. t

Leeaaea Having described my invention, what il claim and desire to secure by Letters-Patent, isz- A refrigerator comprising a metallic casing body, a linin of hard material substantially as specific snugly fitting Within the casing body, and a lining of quicksilver at the inner side of the casing body and between the same and the first-named lining; the casing body and the first-named lining having inwardly-directed flanges at their upper ends, a cover of the same material as the first-named lining threaded into the flange of the same, and a metallic cap removably arranged over the refrigerator body.

In testimony whereof, il affix my signature.
